Effect of post space preparation on apical seal : influence of time interval and sealer

2007

Objective: To assess the efficacy of two sealants to preserve the apical seal after root canal preparation and cementation of posts at 24 h or 72 h after endodontic treatment. Study design: Sixty human single-root teeth were instrumented and obturated using lateral compaction technique with EndoFill® [30] or AH-Plus® [30] and were prepared in one of three ways, leaving a 3 mm gutta percha remnant in all cases: without cast post preparation, with preparation after 24 h or after 72 h. After cementing the posts, the specimens were thermal cycled at 5 and 55?C in water baths, submerged in 2% methylene blue dye for 72 h, embedded in acrylic resin and cut transversally into three 1-mm apical sect…

Nanoliposomas de baicalina y berberina en el tratamiento de afecciones cutáneas

2020

Las enfermedades cutáneas afectan a un gran número de personas. Entre ellas destacan la psoriasis, una enfermedad crónica inflamatoria, y el vitíligo, caracterizada por la despigmentación gradual de la piel. Asimismo, la alopecia representa una de las patologías con mayor impacto sobre la calidad de vida de los pacientes. Las tres tienen en común la ausencia de un tratamiento eficaz. Una de las posibles estrategias terapéuticas que pueden contribuir a resolver este problema sería la administración por vía tópica, ya que presenta una serie de ventajas frente a otras vías. En la presente Tesis Doctoral se propone la administración por vía tópica de productos naturales como coadyuvantes en el …

ChemInform Abstract: One-Step Synthesis, Crystallographic Studies and Antimicrobial Activity of New 4-Diazopyrazole Derivatives.

2010

Summary A number of new 4-diazopyrazole derivatives were prepared by the reaction of 1- R -3-methyl-5(R 1 -substituted)benzamidopyrazoles with a sevenfold excess of nitrous acid in acetic medium. The compounds were tested for activity against Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus faecalis, Listeria monocytogenes, Candida albicans, Candida tropicalis and Paecilomyces varioti . The highest microbial susceptibility was shown by Gram-positive bacteria, with minimum inhibitory concentrations (MIC) in the range 0.5–12.5 μg/mL. For S aureus the R 1 substituents were screened utilizing the Topliss operational scheme. The 4-nitro g…

Follicle Cells of Styela plicata Eggs (Ascidiacea)

2001

Styela plicata eggs are surrounded by large follicle cells that at LM appear as highly vacuolated and columnar in shape; at the apical end of each cell lies a very large and clear vacuole, half of which extends inward. Electron microscope observations show a Single layer of largely spaced box-like follicle cells; the close cell-cell contact at their base is realized by interdigitations. The cell surface shows a peculiar structure, more developed in the latero-basal regions, consisting of a complex of membrane extensions, i.e. microvilli, filopodia and lamellipodia. Filopodia irradiate in all directions towards the adjacent cells and the outermost vitelline coat, thus creating a complex netw…

Caramel odor: Contribution of volatile compounds according to their odor qualities to caramel typicality

2014

Abstract Odor of food constitutes one of the main drivers of the consumers' acceptance. Its characterization thus represents a main challenge for the food industry. Gas chromatography/olfactometry (GC/O) constitutes an intersection between physico-chemical and sensory studies by using the human nose as a detector to evaluate the odor properties of volatile compounds. As GC/O does not make possible the evaluation of mixture of odorants, we propose an original approach to evaluate the impact of compounds on the typicality of caramel aroma by considering their odor qualities in mixtures. Indeed, the present study relies on the main hypothesis that the qualitative properties are as important as…

The Follicle Cells of Styela Plicata (Ascidiacea, Tunicata): A Sem Study

2000

The morphological aspect of the follicle cells of Styela plicata eggs is described by means of scanning electron microscope investigations. The follicular layer is made of spaced, cylindrical box-like cells which are arranged hexagonally. They adhere to the egg through a complex network of membrane extensions making an overall thin layer on the vitelline coat. The walls of the follicle cells are plentifully provided with microvilli, filopodia and lamellipodia, which allow a connection among the cells. At their apical end lies a large vacuole containing a granule, probably involved in secretion. At insemination the majority of spermatozoa is distributed on the apical membrane of the follicle…

Malaria and the heart: Two rare case reports of plasmodium falciparum-associated pericarditis

2017

Malaria is one of the most important parasitic diseases in the world, causing significant mortality and morbidity in the tropical regions1 . Although symptoms can range from a mild fever to severe complicated forms, there are limited published data on cardiac involvement of malaria and only a few studies have been carried out regarding cardiac function in severe malaria2–3. Cardiac involvement in the course of malaria ranges from severe forms with hypatension, shock, circulatory collapse and impaired haemodynamic function, to mild disorders documented by Electrocardiogram (ECG) and echocardiography4–6. Pericardial involvement in malaria is a very rare event7–8. We report here two cases of f…
